I have a lot of species I'd consider 'dream birds' (I'm hopeless!) My list of current obsessions:
Quaker parrots, sun conures, cockatiels, alexandrine parakeets, eclectus parrots (probably my ultimate), African Greys (my ultimate ultimate if they weren't 6k plus in australia), neophemas, polytelis species (superb parrots, regent parrots and princess parrots), king parrots, galahs, green cheeked conures (so cute!), vasa parrots... Lovebirds are growing on me an unbelievable amount too!

Once I'm more confident with parrots I'm sure larger macaws/cockatoos will end up on there as well

Edit: I forgot kakarikis! Dammit zazanomore <3 till you made your thread about them I hadn't considered them. Onto the list they go...
